To all whom, it may concern:

Be it known that I, THOMAS HOLLIDAY, a subject of the Queen ofGreatBritain, residing at Huddersfield, inthe county of York, England,have invented certain new and useful Improvements in Apparatus forProducing and Storing Acetylene Gas, (which has been patented inEngland, No. 5,813, dated March 16, 1896, and No. 885, dated January 12,1897; in France, No. 275,168, dated June 11, 1896; in Belgium, No.121,931, dated June 16, 1896; in Switzerland, No. 13,621, dated January21, 1897; in Italy, No. LXXXVI, 76, dated April 28, 1897; in Spain, No.20,274, dated February 23, 1897 in Portugal, No. 2,409, dated February21, 1897; in Hungary, No. 23,311, dated January 21, 1897; in Austria,No. 47/1,018, dated January 21, 1897; in India, No. 66, dated February17, 1897; in Cape Colony, No. 1,256, dated November 26, 1896; in Natal,No. 12, dated December 31, 1896; in Transvaal, No. 1,276, dated December9, 1896; in WVest Australia, No. 1,538, dated March 2, 1897 in SouthAustralia, No. 3,557, dated February 19, 1897; in Victoria, No. 13,949,dated February 18, 1897; in New South Wales, No. 7,279, dated February20, 1897; in Tasmania, No. 1,831, dated February 22, 1897; inQueensland, No. 3,761, dated February 22, 1897, and in New Zealand, No.9,308, dated February 27 1897 and Ido hereby declare the following to beafull, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to apparatus for producing or generatingacetylene gas produced from the carbids of the alkali metals by theaction of water.

The invention consists of certain parts and details and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

Referring to the drawings, letter A represents a cylindrical holderhaving a water-cistern B above it, but separated therefrom by thediaphragm or horizontal partition G. -A pipe D, passing through thediaphragm and extending down below the minimum level of i the water inthe holder, connects the cistern B with the holder. A drain-cock A isfitted in the bottom A of the holder, and the bottom is preferably madeconical, so as to incline toward this cook.

The generator E is fitted with alid E fixed in position by the screw Eand carbid of calcium is placed in a removable perforated cage containedin this generator. The lower end of this generator is connected toapproximately the highest point of the holder by the pipes F and F and athree-way valve G is placed between the two pipes. Fig. 3 represents asectional view of this valve at right angles to the axis of the plug,showingthe passage G2 through the plug G The plug G may be turned toconnect the pipes Fand F or to stop the passage between them, asrequired, and it may also be turned to the position shown in the figure,so as to connect the pipe F with the waste-pipe F whenit is required toempty the generator.

In the modified construction of plugshown at Fig. 4 the passage Gthrough the plug is formed from the side to theend thereof and the endopening of the passage is permanently open to the passage G coupled tothe generator or pipe F, while the side opening of the passage throughthe plug may be turned toward either of the pipes F F for the purpose ofplacing either of them in communication with the generator.

A gas-delivery pipe H is connected to the top of the generater and ispreferably cou pled to the cooling-coil H located in the cistern B.

To put the apparatus into operation, the holder A is filled with water,and a little water is also placed in the cistern B. The generator may benow charged with calcic carbid, preferably placed in a basket-cage sothat it can be lifted in and out, and after the lid E is secured thevalve G is turned so as to connect the pipes and F F Then the water fromthe holder flows into the generator and the generation of gas commences.In case the gas is generated faster than it is required it firstaccumulates in the generator and drives the water therefrom back intothe holder. After that any gas generated in excess of what isimmediately required also passes by the pipes F and F into the holder,thus displacing the water therein and forcing it up by the pipe D intothe cistern B. This gas remains in the holder until the consumption ofgas exceeds the speed of generation, when such gas passes from theholder through the generator to the pipe H. As the pipe F is coupled tothe holder at its highest point, water is not again admitted to thegenerator until the gas accumulated in the holder is practicallyexhausted.

To recharge the generator, the tap G is turned to open communicationbetween the pipes F and F and the lid E opened, the residue and water inthe generator thereupon escaping through the pipe F ator is' thenrecharged with carbid, the lid E closed and secured again, and the tap Gturned to reopen communication between The generpipes F and F when theapparatus is again ready to produce gas when gas is withdrawn from it.

In all cases the pipesFF and tap Gshould be so arranged that there shallbe no dip or place for the lodgment of water sufficient to seal thesame, and the pipe H should be inclined to the generator.

Having now described my invention, I declare that what I consider new,and desire to secure by Letters Patent, is

1. An acetylene-gas apparatus, comprising a cistern, a holder below thecistern and into which a pipe from the cistern extends nearly to thebottom thereof, a coil of pipe in the cistern and adapted to beconnected with the service-pipe, a gas-generatorv connected directlywith the said coil, and a pipe leading from the lower end of thegenerator into the upper end of the holder and provided with a three-waycock, substantially as described.

2. An acetylene gas apparatus consisting of a water-holder having adrain-pipe in its bottom, a cistern above the holder and separatedtherefrom by a horizontal partition, a pipe leading from the partitiondown to within a short distance of the bottom of the holder, a coil ofpipe in the cistern and adapted to be connected with a service-pipe, agenerator having its upper end connected with the said coil, saidgenerator being outside of the holder and on about a level therewith, apipe leading from the upper end of the holder to the lower end of thegenerator, and a threewaycock in said pipe, substantially as hereinshown and described.

In testimony whereof I affix my signature in presence of two witnesses.

THOMAS HOLLIDAY.
